malloc_stats(3) Library Functions Manual malloc_stats(3)
malloc_stats - print memory allocation statistics
Standard C library (libc, -lc)
#include <malloc.h>
void malloc_stats(void);
The malloc_stats() function prints (on standard error) statistics
about memory allocated by malloc(3) and related functions. For
each arena (allocation area), this function prints the total
amount of memory allocated and the total number of bytes consumed
by in-use allocations. (These two values correspond to the arena
and uordblks fields retrieved by mallinfo(3).) In addition, the
function prints the sum of these two statistics for all arenas,
and the maximum number of blocks and bytes that were ever
simultaneously allocated using mmap(2).
For an explanation of the terms used in this section, see
attributes(7).
